Why didn’t the Mail show the evidence?
This is the evidence:
“The sea dataset used by Thomas Karl and his colleagues – known as Extended Reconstructed Sea Surface Temperatures version 4, or ERSSTv4, tripled the warming trend over the sea during the years 2000 to 2014 from just 0.036C per decade – as stated in version 3 – to 0.099C per decade. Individual measurements in some parts of the globe had increased by about 0.1C and this resulted in the dramatic increase of the overall global trend published by the Pausebuster paper. But Dr Bates said this increase in temperatures was achieved by dubious means. Its key error was an upwards ‘adjustment’ of readings from fixed and floating buoys, which are generally reliable, to bring them into line with readings from a much more doubtful source – water taken in by ships. “
Prior to 2003 ocean temps were taken from buckets hauled up into ships or ship intake ports. Not very accurate and Almost exclusively from shipping lanes, not really measuring globally.
After 2003, the (billion dollar?) ARGOS buoy system went online. A global set of buoys that float around all the oceans, dive to a certain depth, surface, then transmit temperature data to satellites. High tech, global and accurate.
The Karl paper in question threw out the more accurate (and cooler) buoy data and matched it to the less accurate (warmer) ship intake data.
My argument to climate scientists:
If this (very expensive) global buoy system is so off, then let’s scrap it and save the taxpayer the millions of dollars/year this apparently inaccurate system (Karl 2015) is costing.
